Hello,

The normal glucose reading first thing in the morning (called the 'fasting glucose level) should be between 70 to 100 mg/dL. Levels between 100 and 125 indicate prediabetes and higher than 125 mg/dL suggest diabetes.

Another test for the blood sugar level is called the “random blood glucose” - this test may be taken at any time in relation to eating or drinking and can be administrated at any time. A level higher than 140 mg/dL can indicate prediabetes. A level above 200mg/dL indicates diabetes.

The third type of blood sugar test is the after meal or post-prandial test. This should be less than 140mg/dL. Higher levels indicate diabetes.

There is no specific test for a before meal test - this is called the random blood sugar test.

I hope this helps.

Your answer was extemely helpful. How long after you eat should you test? I've ben told I'm prediabetic and will probably be asking more questions at a later time

Thank you very much

The post prandial test should be done 2 hours after a meal.

You are welcome to ask more questions.

I hope this helps.
